FLUSHING-CUSPIDOR.

Specicaton of Letters Patent.

' Patented Mar. a, i915.

Application filed August l), 1914. Serial No. 855,945.

T0 all whom it may concern?" Be it known that I, HENRY F. BLACK, a citizen of the United States, and a resident of Sioux City, in the county'of Woodbury and State ofiIowa, have invented certain new and useful Improvements in Flushing- Cuspidors, of which the following is a speciiication.

The present invention relates to euspidors.

'Ihe invention has for its primary object the production of an improved automatically-flushed sanitary cuspidor, adapted for use in dwellings, business and public places.

Another object of the invention is the construction of an article of this class provided with a closure controlled by the flushing apparatus.

With these and other objects in view, the invention, consistingy in the construction, combination and novel arrangement of parts, will be fully understood from the following description, reference being had to the accompanying drawings, which form a part of this application and in which like characters of reference indicate corresponding parts throughout the several views, of which,-

Figure 1 is a front elevation of a cuspidor constructed tion; Fig. 2 is a vertical section of the same; Fig. 3 is a plan of the same; and Fig. 11 is an enlarged side elevation of the controlling -lever and members associated therewith.

Although I have illustrated and herein describe the preferred embodiment of the invention, I would not be understood as being limited to the speciic structure chosen for illustration, for various modifications and ,alterations in the details ofcons-trucof partsl may be tion and .arrangement from the spirit and made without departing scope of the invention as defined in the appended claims.

The invention contemplates a structure comprising a receptacle provided with an outlet, a closure for the receptacle, and means for automatically opening the closure and coincidentally flushing the receptacle, all of which will presently be made clear.

Referring, now, to the illustrations, 5 represents the receptacle, or bowl, of any suitable material, shape and size, and having in its lower portion a duct, 6, adapted at its lower end for sewer connection and communicating, through a sewer-trap, 7 with in accordance with the inventhrough the passages the upper part, 8,-of the bowl, the walls of which part preferably Hare outwardly in a manner common to articles of this class. The rim of the latter part forms an inner annular duct, 9, provided at intervals with eduction ports, 10, and communicating with an induction port, 11, fed by a pipe, 12, leading from the upper end'of a cylinder, 13, within which operates a piston, 14, carrying a piston-rod, 15, connected by links, 16, pivoted upon projecting pins, 17, mounted upon mated lids, 18, hinged, as at 19, to swing upwardly and oppositely to each other.

rI`he lower portion of the cylinder is provided with ports, 2O and 21, communicating with a valve-casing, 22, having an induction pipe, 23, for connection with a source of water pressure. The valve-casing communicates with the duct, 6, through a port, 24C; and incloses a two-way valve, 25, having a diametrical passage, 26, normally registering with the ports 2O and 24. 27 is the induction passage of the valve and leads to the port 26.

The valve-stem, 28, is radial arm, 29, (Figs. 1 by a link, 30, with a crumed on a bearing, 32, mounted on the base of the receptacle. The lever is retracted by a spring, 33, interposed between the lever and the receptacle.

By virtue of the structure now disclosed it is clear that when the foot-lever is depressed the valve will be so turned that the port 27 will receive water from the supply, and pressure ports 26 and 21, will force the piston upwardly and enter the eduction chamber 11 and 12. As the piston raises the lids are thereby opened to admit the deposit of waste matter into the receptacle. When the foot-lever is released closed receptacle having an outlet therein, of a valved passage between the source of provided with a and 4:) connected, foot-lever, 31, fulentering the cylinder through f the piston and closure,

if ing the latter,

and the receptacle for Hushand means controlled by the valve for openin the receptacle coincidentally With the ushing.

In a cuspidor, the combination with a source of Water pressure and a receptacle having an' outlet therein, of a closure for the receptacle, pressure-operated means for opening said closure and including a cylinder, a-piston and a connection between a normally-closed passage to admit Water for flushing the receptacle and controlled by said-means, and

Water supply a valved passage between the source of water pressure and cylinder.

In a cuspidor, the combination With-*a source of water pressure, and a receptacle having an outlet therein and a hinged cover l therefor, of means for opening the cover and flushing the receptacle, said means including a cylinder, a piston, a connection be` tween the piston and cover, a valved passage between the source of Water pressure and the cylinder, and a passage between the upper portion of the receptacle and the cylinder.

In testimony'whereof I have hereunto set my hand in presence of two subscribing witnesses.
